I agree it would be great if Tails worked better on
In the case at hand, the behavior you're describing suggests
a computer+drivers without hardware acceleration for at least some
graphics features used by GNOME Shell, which would make GNOME fallback
to software rendering, which indeed can use lots of CPU power.
You can disable some of these costly graphics effects in GNOME Tweaks
(gnome-tweaks package), but not all of them.
Ideally, GNOME would detect such a situation, and automatically
disable costly graphics effects (animations, see window content while
moving, etc.). It would be nice if someone checked if upstream
already considered this.
